Important note to software companies and developers: European pro-consumer countries have gone the route of statutorily limiting the scope of arbitration and other presumptively unfair clauses in consumer contracts. As a result, in such pro-consumer countries, I cannot offer the end user a software license with the standard US happy-go-lucky arbitration clauses, disclaimers and limitations of warranties. Normally, it is best to include Indemnification Clause (see below) which makes the distributor in that country liable for making EULAs compliant with the local law. Read Software Licensing Issues for US Businesses in Europe and Japan to get an idea of potentially problematic software/mobile application licensing clauses in foreign jurisdictions.
Limitations/Disclaimers of Warranties clauses are pretty standard but you need to know which ones to choose for your particular business model because not all liability can be disclaimed and you risk a lawsuit if you are too greedy.
Non-Solicitation, Non-Circumvention clauses are particularly useful if you are a middle man or woman that does not want to be cut out of the deal. For example, you are a real estate broker or you are running a website that matches buyers and sellers. So, you include non-solicitation and non-circumvention provisions which prevent parties from dealing directly with each other in order to avoid paying your fee.
Entire Contract Clause basically means that the contract represents the complete and final agreement. It prevents people from claiming there are some terms not listed in the contract that affect your deal.
Reporting to credit agencies gives you more leverage in debt collection because clients are less likely to default on their debt. Reserving your right to pursue debt via debt collection agencies gives you another advantage, even though the debt collection agencies are required by law to stop contacting the debtor if he or she tells them to cease communication.
